发明名称 Imaging apparatus
摘要 A camera capable of compensating for facial field of a person to a proper brightness, and maintaining the luminance scale of the background, comprising an imaging portion for generating the picture data of the person; a gamma compensator for performing gamma compensation for the picture data; a facial field detecting portion for detecting a facial field from the picture data; a photometric portion for exposure metering value of the facial field detected by the facial field detecting portion; an exposure controlling portion for calculating a target exposure amount in response to the output of the photometric portion and controlling exposure depending on the target exposure amount; and a gamma compensation controlling portion for determining a luminance scale characteristic in accordance with the target exposure amount, wherein the gamma compensating portion is controlled on the basis of the luminance scale characteristic determined by the gamma compensation controlling portion.
